General

AM5 series microcomputer protection device are applicable to the user substation which the input voltage is 35kv or below. AM5 can be used to protect and control the user substation, and is be widely used to Power Industry, Water conservancy industry, Traffic Industry, Oil industry, Chemical industry,Coal Industry, Metallurgical Industry and so on.

The advanced and reliable protection principles and algorithms are used in AM5, and AM5 series protection devices have so many advantages such as anti-jamming performance, high reliability, flexible way to achieve protection, communication uses redundancy design. The device has independent high-precision current measuring circuit,16DI、10 DO and so on. The AM5 can be used to communicate with The Acrel-2000Z power monitoring system to support Unattended substation system.
